I was surfing through IMDB today and came across an entry on a Live Action Dragonball movie. I had heard rumors and, seeing as nothing was happening, assumed that the rumors were false. Anywho, the IMDB link is http://www.imdb.com/title/tt1098327/

Chow Yun Fat is Master Roshi!!!!!!

I also found some concept video about the movie. That's at http://youtube.com/watch?v=DTZIwuc35cE
